What was done, kept
A senda is a record. The ground wears where people walked, and the next person reads the way from it. Nobody wrote it down.
Agents leave no such trace unless something keeps it. A run reads a document, calls a model, sometimes waits for a person, and ends. If its only record lives inside the product that ran it, the one who acted also keeps the minutes.
Semant keeps them somewhere else. Line sends each run to Semant step by step, in OpenTelemetry, and Semant stores every span as it arrived. A span it cannot hold whole it refuses, and says why.
Line sends what was done: which agent, which step, how long, which model, how many tokens, where a person was asked. It does not send what was said. Prompts and replies stay in Line.
A company can let its agents move fast when it can read back every move they made, one run at a time, at nine the next morning.
In the mark, Semant is the line that stays in colour after the walking is done.
